UNITED STATES PATENT OFFICE 2,239,791 LINE GUIDE Julius Lemperle, Salt Lake City, Utah Application September 23, 1940, Serial No. 357,893

3 Claims.

line .guide for fine or heavy type so that the guide having parallel spaced apart line rules may be separated or drawn closer together if desired to place one rule along each side of the line of printing being copied or read.

A still further object is to provide a line guide which may be attached to the usual copy finger of all Intertype or Linotype machines and used in conjunction wherewith, the movable part being adjustable by a cam action to grip the walls of the slotted head of the stationary head of the lower side to permit spacing the two rods apart as desired.

A still further object is to provide a line guide which may be attached to the guides used'by stenographers and the like and used in the same manner, the vast difference being that the line above and below the line being copied will be covered thereby eliminating any possible chance of error.

A still further object is to use the guide on books having very fine print to enable a person reading the book to concentrate on the single line facilitating the reading of fine print on either side.

These objects I accomplish with the device illustrated in the accompanying drawing in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawing,

Figure 1 shows the use of my device attached to a copy holder for typists or printers, parts cut away.

Figure 2 shows a side elevation of Figure 1.

Figure 3 is a plan view of the device removed from any holders showing the main essential features.

Figure 4 is an inverted view of Figure 3.

Figure 5 is an edge view of Figure 4.

Figure 6 is an edge View of the device attached I to a copy holder paper clamp.

Figure 7 is a plan view of Figure 6.

In the drawing I have shown a copy table as A, having a stand. B on which it is adjustably mounted by wing nuts and bolts at the heads of spaced apart legs C of the stand B. The table A is provided with the usual vertical rod 5 spaced from the table A by the ends 6 being bent back and secured to the table in the conventional manner.

Onto this rod 5 I mount my line guide which consists of a finger clamp D attached to the rod 5 by the guide cylinder 1 on the back side or stationary part of the finger clamp D. Thus, the clamp and guide may be raised and lowered on the rod 5. i

The guide of my invention consists mainly of a lower guide bar I0 having an L head II on the end thereof and which bar is beveled along the upper edge adjacent the copy paper to provide ruled spaces l2 for guiding printers and type setters in their work.

The head II is slotted at I3 and the adjusting feature of the device is carried in said slot I3. The head M of the upper guide bar I5 is formed as a channel enclosing the face, one edge, and part of the back on one side and the other edge of the head I I of the bar I0. This provides vertical movement of the upper guide bar l5 relative to the lower guide bar. ID. The adjustment is provided by a finger nut l6 attached to a rotatable shaft having the end enlarged and formed oblong in that portion thereof which is carried within the slot l3. Thus, by turning the finger nut Hi, the oblong portion will grip the side walls of the slot I3, locking the upper guide bar l5 spaced any desired distance from the guide bar Ill. The head II is provided with spaced apart holes l9 to permit attachment of the head to any Linea-time, Intertype, Linotype or other similar devices securing the spaced guide bars to the sliding head of any of these machines which use a copy holder on a copy holder table. A screw 2| is screwed into the end of the oblong area of the finger nut IE to hold the nut in place.

It will also be obvious that the same type of a device may be made to attach the device over the reading surface of a newspaper, book, or the like, just so long as a vertical rod is provided to hold the line guide bars parallel to the reading matter, and such modifications and variations are considered a part of my invention and within the scope of the claims.

Having thus described my invention I desire to secure by Letters Patent and claim:

1. A line guide comprising a lower bar having an L-shaped head; another bar mounted on the L-shaped head, said latter bar being verti- 3. A line guide comprising parallel guide bars, one of which has the other adjustably mounted thereto to provide for adjustment of the said one bar to. vary the space between said bars.
